The EvtPacketQueueSetNotificationEnabled callback function is implemented by the client driver to perform client-specific processing when there are new packets received in the specified queue's ring buffer.
Syntax
EVT_PACKET_QUEUE_SET_NOTIFICATION_ENABLED EvtPacketQueueSetNotificationEnabled;
void EvtPacketQueueSetNotificationEnabled(
[_In_] NETPACKETQUEUE PacketQueue,
[_In_] BOOLEAN NotificationEnabled
)
{...}
Parameters
[_In_] PacketQueue
A handle to a packet queue.
[_In_] NotificationEnabled
A value of TRUE requests that the client enable packet queue notification. A value of FALSE requests that the client disable packet queue notification.
Return value
None
Remarks
Register this callback function in your EVT_NET_ADAPTER_CREATE_TX(RX)QUEUE callback. Set the appropriate member of a NET_PACKET_QUEUE_CONFIG structure when you are initializing the structure with NET_PACKET_QUEUE_CONFIG_INIT, then call NetTx(Rx)QueueCreate.
NetAdapterCx serializes this callback function along with the packet queue's EVT_PACKET_QUEUE_CANCEL and EVT_PACKET_QUEUE_ADVANCE callback functions.
For more info and a diagram showing the NetAdapterCx data path polling model, see Transmit and receive queues.
